I had a Bluesky account at the hight of the twitter migration. At the time it seemed promising and their were a lot of cool tools,both first and third parties, some of them still exist

I had to delete my account because I was at a point where I was overwhelmed by the amount of account I had, but I just got back and have been heating and seeing that bluesky has lost a lot of followers

So my question, did most people go back Twitter? Or did they disperse to other social medias across the internet. And why did people leave in the first place?
